Specification of Letters Patent.

Applicationzled November 21, 1917. Serial No. 203,240.

To all whom zt may concern.'

Be it `known that I, EINAR UFFELMANN, a citizen of the United States, and a resident otl the borough of Manhattan, city and State ot' NewYork, have invented certain new and useful Improvements in Containers, ot' which the following is a specification.

My invention relates to containers and more particularly to containers made of a, soft material from which the contents are ejected by compression of the sides, e. g., tooth paste tubes, and is characterized by the provision of a. neck for such containers and a longitudinally slidable cap adapted to act as a closure for the orifice from which the contents are ejected.

One form of tooth paste tube and the one which probably is in more general use than any other -form has been provided with a screw cap. A screw cap is inconvenient to manipulate. requiring usually both hands of the operator, the threads are liable to be stripped, and the cap lost.

One form of tooth powder container has been provided with a neck having an opening and a. rotatable cap having openings on said neck. the openings in the neck and cap being adapted to be brought into registry by the rotation of the cap. i

Another form of ,tooth powderbox has been provided with a longitudinally slidable cap operating within an upstanding peripheral fiange secured to the shoulder of the box. A structure 'of this character would not, however, be adapted for use with tubes havingr soft metal `sides in which the contents are ejected' by compression as the accidental compression of such sides would force up the cap by the pressure of the conn tents against the cap and permit t-he contents to issue from the container. The closing of the cap would also present objectionable features when used with paste as the downward pressure of the cap would force an addi-- tional and undesired quantity of the contents from the container.' y

In my invention, I-have overcome to a great extent the objections above enun'nerated by providing'an ,upstanding neck for the lcontainer which acts as a reservoir for the contents and prevents the pressure thereof -from acting directly against a cap which' is longitudinally slidable thereon, in the direction in which said cap is ada ted to slide and preventing` the cap from lrectly pressing on said contents when, the cap is pressed down. My structure is more conratentea .rely s, 1919. j

veniently operated as the cap may be closed by press-ing the cap against some convenient object, thus obviating Vthe necessity of the operator employing both hands, as is necessary in the first and second structures above referred to; there are no threads to strip and the cap, being non-separable from the container, cannot be lost. Other objects of my invention' will more fully appear in the following description ot' the drawings accompanying this specification:

'Figure 1- is a side elevation of one example of my invention showing a vertical section of the cap; Fig. 2 is a section of Fig. Y

1 on the line 2-2; Fig. 3 is a vertical section of one example of my invention; Fig; 4 is a side elevation of a modification of my invention with one of the elements partly broken away; F ig. 5 is a vertical section of the modification shown in Fig. l and Fig. 6 is a section of Fig. 5 on the line 6 6.

Referring tothe drawings, a Vcontainer 5, preferably formed of soft metal such/,as lead, has an upstanding neck 6 having arropening E and provided with a longitudinally disposed groove 8, extending from the upper edge of said neck to .a position approximately half way between the upper edge of theneck and the top of thecontainer, and a longitudinally disposed groove 9 extending from a position below the top edge of the neck 6 to the top of the container 5. 'The' grooves 8 and 9 are joined by a by-pass groove 10. Co-axial with the neck 6 is a cap 11 of the usual construction having an inturned lug 12 adapted to engage 'the groove 8 when in operative position. A modification of my invention, shown in Figs. 4, 5 and 6, shows a neck 13 similar to the neck 6 described for lthe modification shown in Figs.

A1, 2 and 3 and provided with oppositely disengage pass groove 10. It is then rotated until the i lug 12 is inr the'groove 9 when the capmay be moved longitudinally away from the container 5, thus exposing the ley-pass groove 10 and. portions of* the rgrooves 8 and 9.

6 a dropof solder or In order to prevent the cap from becoming disengaged from the container 5, the bypassygroove may be closed in a suitable man- "ner such as, for instance, by placing therein b breaking down the wall of the groove so that the said Wall partally covers and obstructs it. In this Way the lug 12 is confined to the groove 9 and the cap 11 is prevented from becoming Sepa- 10 rated from the neck- 6 -of the container 5,

while the cap 11 is longitudinally slidablc on the 'neckl and the opening 7 may be covred or uncovered at will. In the modification 'shown in Figs. 4, 5 and 6, the cap 14 having the lugs 17 and 18 in alinement with the sides thereof so that the cap may be vslipped over the top of the neck 13, are placed over the neck 13 of the. container 5. The lugs 17 and 18 are then turned in to oc- 2) cupy a position substantially as vshown in the 'Fig ,5, so that they engage the grooves 15 and 16,as hereinbefore described. The cap 14 is prevented from becoming separated from the container 5 by the lugs 17 and 18 5 striking the stop Walls at the upper end of v the grooves, as Will be readily apparent from y an ezamination of the drawings. It is, of course, obvious that instead of employing lugs I may create depressions in the walls of the cap.

Various modifications maylbe made in the details of my invention without departing from the spirit of the appended claim.

I claim:

A container having a,neck closed at the top and provided vvith a discharge opening in the side thereof communicating with the interior, a closure cap comprising an i111- perforate sleeve linearly slidahle upon said neck so as to cover said opening in its inner position and uncover the opening in its outer position, the adjacent peripheral surfaces of neck and cap inthe vicinity of the opening being at all times in close contact, and means for limiting Ithe extent of outward movement of the cap,

1 Intestimony whereof I have hereunto set my hand.
